Chemotherapy Plus Interferon Alfa Alone or With Radiation Therapy and Peripheral Stem Cell Transplantation in Treating Patients With Stage III or Stage IV Follicular Non-Hodgkin's Lymphoma

2014-08-27 03:58:48 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Interferon alfa may interfere with the growth of cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and radiation therapy and kill more cancer cells.

PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy followed by interferon alfa alone or combination chemotherapy plus radiation therapy and peripheral stem cell transplantation in treating patients who have previously untreated stage III or stage IV follicular non-Hodgkin's lymphoma.

Description

OBJECTIVES: I. Compare the progression free and overall survival, toxicity, and mortality of marrow ablative chemo/radiotherapy in addition to peripheral blood stem cell transplantation and interferon alfa maintenance therapy versus interferon alfa maintenance therapy alone in patients with follicular non-Hodgkin's lymphoma.

OUTLINE: This is a randomized study. All patients receive 8 courses of cyclophosphamide/vincristine/prednisone (CVP) chemotherapy. Cyclophosphamide and vincristine IV are given on day 1, along with oral prednisone on days 1-5. Courses are repeated every 3 weeks. Patients are randomized to receive one of two treatments 4 weeks after completion of CVP chemotherapy if a partial or complete response is achieved and there are less than 15% monoclonal B-lymphocytes in the bone marrow. Patients randomized to arm I receive interferon alfa subcutaneously 3 times per week for a maximum of 3 years. Patients randomized to arm II receive cyclophosphamide IV followed by subcutaneous filgrastim (granulocyte colony-stimulating factor; G-CSF). Leukapheresis begins after leukocyte, platelet, and CD34+ levels recover and lasts 3-4 hours on 2-3 consecutive days. If an insufficient number of stem cells are collected from the peripheral blood, bone marrow harvesting is performed. After stem cell collection, a conditioning regimen consisting of cyclophosphamide IV on days -4 and -3 and total body irradiation on day -1 is administered. Stem cells are infused on day 0. If granulocyte and platelet counts recover within 8 weeks, patients receive interferon alfa maintenance therapy as in arm I. Patients are followed every 4 months until death.

PROJECTED ACCRUAL: A total of 469 patients will be accrued for this study within 5 years.

Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
